Systems and methods for self-contained certificate signing request in delegation scenarios

ABSTRACT

A platform security system and method improve security by binding an identity of a self-contained certificate signing request (SC CSR) requestor to the SC CSR to prevent malicious tampering, such as man-in-the-middle attacks. In at least one embodiment, the requestor, such as a client computer system or other source of a request, requests certificates from a certificate authority (CA). Binding the identity of the SC CSR to the requestor can prevent unauthorized system and/or data access and potentially resultant unauthorized access, malicious tampering, such as man-in-the-middle attacks, and other unauthorized actions or observations. Validation can be performed at the CA on the SC CSR to determine the integrity of the requestor and authorization to receive certificates before the CA sends the certificate to the requestor.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority to U.S. Provisional Patent Application No. 63/030,287, filed May 26, 2020, entitled “Systems and Methods to Enhance Technology Including Employment and Security Related Technology”, which is incorporated herein by reference.

BACKGROUND OF THE DISCLOSURE Field of the Disclosure

The present invention relates to supervised learning processing, and more particularly to a system, method, and computer program product involving self-contained signing certificate signing requests between requestors, intermediaries, and certificate authorities.

Description of the Related Art

In various communication implementations, in order to provide security between various entities, unique certificates identifying entities are used. Such certificates are particular to each entity. The certificates can be referred to as public certificates and allow other entities to confidently know the identity of specific entities.

For various implementations, an entity referred to as a requestor, requests for a certificate to be issued from a certificate authority or CA. The certificate can be a new certificate or an updated/revised certificate. The request may be in the form of a certificate signing request or CSR. The CSR can be sent directly from the requestor to the CA. In these instances, the CSR is typically implemented as a secure point-to-point transaction between the requestor and the CA. The CA sends the new or updated/revised certificate to the requestor.

In certain cases, there may be a desire to implement a mediator or intermediary between the requestor and the CA. The use of intermediaries may be driven by business scenarios or business logic. For example, an intermediary may be used to provide authorization and deployment to requestors for requesting of certificates. Example implementations can provide for the use of the CA as a facade and providing authorization or added business logic such as an abstraction layer through the intermediary which can allow for seamless CA replacement or redirection. Intermediaries may also support and be specific to different server computers that provide services.

Security concerns arise when the intermediary is not a trusted component/entity. In certain instances, the intermediary can be a third party component/entity that is not in the control of an enterprise that controls the requestor and/or the CA. Because the request or CSR is propagated via the intermediary, the request or CSR can be compromised. The intermediary may modify propagated CSRs or even generate different CSRs to maliciously impersonate different identities. For example, a malicious intermediary may generate its own private key, send a modified or spoofed CSR, under the guise of a requestor, and receive a public certificate from the CA that identifies the requestor. The malicious intermediary using the public certificate is able to impersonate the requestor.

SUMMARY

A method, system and computer-readable medium providing a self-contained certificate signing request (SC CSR) that comprises determining an entity that requires a certificate, wherein the certificate identifies the entity to other entities; binding an identity of a requestor to the SC CSR; sending the SC CSR that is bound with the identity to one or more intermediaries which is passed along to a certificate authority (CA), wherein the CA performs a validation on the SC CSR that is bound with the identity to verify identity and authorization to receive certificates by the requestor; and receiving the certificate from the CA.

DETAILED DESCRIPTION

A platform security system and method improve security by binding an identity of a self-contained certificate signing request (SC CSR) requestor to the SC CSR to prevent malicious tampering, such as man-in-the-middle attacks. In at least one embodiment, the requestor, such as a client computer system or other source of a request, requests certificates from a certificate authority (CA). Binding the identity of the SC CSR to the requestor can prevent unauthorized system and/or data access and potentially resultant unauthorized access, malicious tampering, such as man-in-the-middle attacks, and other unauthorized actions or observations. In certain implementations, the binding of the identity to the requestor with the SC CSR is through a “current” private key (PK) that is owned by the requestor. The SC CSR is passed from the requestor through one or more intermediaries before the CA receives the SC CSR. The one or more intermediaries are not able to modify or tamper with the SC CSR, because the SC CSR is bound to the identity of the requestor through the current PK. Implementations provide for the CA to include a component (e.g., plugin) that validates the SC CSR.

FIG. 1 shows an example platform security system that implements self-contained certificate signing requests between requestors, intermediaries, and certificate authorities. The system 100 can be part of a or accessible to other systems, such as a service mesh. In various implementations the system 100 is used for deployment of services. Implementations provide for runtime platform 102 to deploy one or more service(s) or deployed service(s) 104. The runtime platform 102 may include a deployment component 103 that deploys deployed service(s) 104.

Embodiments can provide for the runtime platform 102 and the deployed service(s) to have particular unique identities. Implementations provide for the certificates to be used for the unique identities. In particular, such certificates are public certificates or PC, that are recognized by other entities.

In various implementations, runtime platform 102 requests for a new or updated certificate or certificates, which are public certificates or PC. The runtime platform 102 may be referred to as a client or requestor. In certain implementations, the runtime platform 102 requests for a new PC for service 104 to be deployed. In other words, when a service 104 is to be deployed, the service 104 will need a PC when the service is 104 is bootstrapped. The deployed service(s) 104 may interact with themselves and/or other entities and use the unique PCs to identify themselves to each other and/or the other entities.

The PC is used to identify service 104. The request for the PC is made before the service 104 is started or deployed. In certain cases, the runtime platform 102 or the deployed service(s) 104 may have expiring PCs which are to be renewed/replaced. Therefore, a request for a new PC is performed. For example, deployed service(s) 104 may be implemented through a service mesh which provides a PC with a short term expiration. The deployed service 104 needs to renew the expiring PC to continue to be operational. Other scenarios that include the use of a PC involve work stations (users) accessing test/production environments through a bridge that requires the PC to validate the work stations (users).

Implementations provide for the runtime platform 102 to include currently in use private key 1 or PrK_1 and current public certificate or PC_1. A self-contained certificate signing request or SC CSR 106 is sent by the runtime platform 102 to request for a PC either for the runtime platform 102 or one or more deployed service(s) 104. A public key 2 or PuK_2 is signed by PrK_1. The SC CSR 106 includes PC_1 and PuK_2. A binding is therefore performed with the identity of the runtime platform 102 which is a requestor through the PrK_1.

One or more certificate issue (CI) services or intermediaries 108 receive the SC CSR 106. In certain implementations, the runtime platform 102 as a sender establishes a transport layer security (TLS) connection with the one or more CI services or intermediaries 108 through the pair of (PrK_1, PC_1). The identity of runtime platform 102 is established with CI services or intermediaries 108 for authentication and authorization. In certain implementations, a JSON Web Token or JWT token can be possessed by runtime platform 102. The JWT token is used for authentication and authorization. In such implementations, the JWT token is signed by a private key of an application such as OneLogin in order to authenticate the platform 102 to the one or more CI services or intermediaries 108.

In implementations that make use of JWT tokens the following can be performed. In instances of first-time certificate or PC generation, using a JWT token of the runtime platform 102 (i.e., JWT bearer token), the same processing pattern described above can used. The JWT token is generated with metadata, that effectively gives the JWT token the property of a PC. Prior to performing a two factor authentication (2FA) with the OneLogin application, the runtime platform 102 can first generate private key, public key pair (PrK_1, PuK_1), where the PuK_1 is included with a request to the OneLogin application. The JWT token will include PuK_1 and the SC CSR 106 will include the JWT with PuK_1 which is used to verify the signature of the public key or PuK_2 that was signed by PrK_1. The JWT token also includes the signature of PuK_2 that was signed by PrK_1.

The use of JWT tokens can lead to an unbounded growth of a certificate or PC size from periodic renewals of the PC, since each renewal of a current PC may be added to the SC CSR 106, and consequently added also to the generated certificate or new PC. To alleviate this potential issue, the JWT token or the current PC is not included in the the body of the SC CSR 106. As long as the SC CSR 106 includes the signature of PuK_2 that was signed by PrK_1, the JWT token or the PC_1 can be sent outside or separate from SC CSR 106.

The intermediaries 108 may or may not be trusted entities. In certain cases, intermediaries 108 can be third party entities that provide a service. The intermediaries 108 are implemented to provide functions that can be related to business scenarios or business logic. For example, particular intermediaries 108 may be used to provide authorization and deployment to requestors for requesting of certificates. In certain implementations, CI services or intermediaries 108 are used to manage computing resources, such server computers. The intermediaries 108 can operate sequential or in parallel. It is to be understood that with multiple CI services or intermediaries 108, operations can also take place at different times or sequences. The one or more intermediaries 108 are not able to modify or tamper with the SC CSR 106, because the SC CSR 106 is bound to the identity of the runtime platform 102 through the PrK_1. The CI services or intermediaries 108 merely pass on the SC CSR 106 to a certificate authority (CA) or vault 110.

The CA (vault) 110 may or may not be a trusted entity. The CA (vault) 110 issues new or replacement PC to a requestor, such as runtime platform 102. Implementations further provide for the he CA (vault) 110 to include a component or plugin for SC CSR validation 112. As discussed, the CI services or intermediaries 108 can be implemented to provide authorization of new/renewed certificates or PCs to the requestors (e.g., runtime platform 102). However, in certain instances, the CI services or intermediaries 108 may not be consistent entities in the processing of such requests. In other words, the CI services or intermediaries 108 may or may not be available to identify and validate the identity and PC request of requestor (e.g., runtime platform 102).

The plugin for SC CSR validation 112 is used to identify that the SC CSR 106 is self-contained and includes proof of identity of the requestor (e.g., runtime platform 102). The plugin for SC CSR validation 112 validates the integrity of the SC CSR 106, and uses the PC_1 to verify the signature of PuK_2 signed by Prk_1 which proves that PrK_2 is owned by the identity in PC_1. The identity being that have the requestor (e.g., runtime platform 102).

If the SC CSR 106 is validated the CA (vault) 110 provides a new or revised PC 114. The new PC 114 can be passed through the one or more CI services or intermediaries 108 to the requestor (e.g., runtime platform 102). In certain implementations, the CI services or intermediaries 108 are bypassed, and the new PC 114 is directly provided to the requestor (e.g., runtime platform 102).

Implementations further provide for the system 100 to include an identity access management (IAM) service 116. The CI services or intermediaries 108 and CA (vault) 110 are provided “can act on behalf of” communication 118 to the IAM service 116. In particular, the IAM service 116 can provide identifiers, such as a source ID from the current/prior PC, and a target ID from the SC CSR 106.

FIG. 2 depicts an example process 200 for self-contained signing certificate requests between requestors, intermediaries, and certificate authorities.

. At operation 202, the process 200 starts. At operation 204, a requestor, such as runtime platform 102 or deployment component 103 of runtime platform 102 deploys one or more deployed services 104, where the one or more services are entities that are to be identified by other entities.

At operation 206, the runtime platform 102 as a requestor determines and requests new or renewed/updated certificates for itself and/or the one or more deployed services 104. When a deployed service 104 is deployed, a new certificate may be needed during bootstrapping of the deployed service 104. In certain instances, the runtime platform and/or the deployed services 104 may have an expiring certificate that is to be renewed or replaced.

At operation 208, the runtime platform 102 as a requestor creates a self-contained certificate signing request or SC CSR 106. The SC CSR 106 binds the identity of the runtime platform 102 by including, for example, a public key 2 or PuK_2 is signed by a current private key 1 or PrK_1 and including a current public certificate PC_1. In certain implementations when using JSON Web tokens or JWT tokens, a JWT token is used as a public certificate by runtime platform 102. The JWT token will include the current public PuK_1 which is included in the SC CSR 106, and is used to the signature of the public key or PuK_2 that was signed by PrK_1. The JWT token also includes the signature of PuK_2 that was signed by PrK_1.

At operation 210, the runtime platform 102 sends the SC CSR 106 to one or more certificate issue (CI) services or intermediaries 108. In certain implementations, the one or more CI services or intermediaries 108 perform certain functions which may be related to business based scenarios and business logic. In various implementations, the CI services or intermediaries 108 provide certificate authorization and deployment functions. Because the SC CSR 106 is bound to the requestor runtime platform 102, the SC CSR 106 cannot be tampered, spoofed, or changed. The one or more CI services or intermediaries 108 merely passes on the SC CSR 106.

At operation 212, certificate authority or CA (Vault) 110 receives the SC CSR 106 to provide for a new or renewed certificate to runtime platform 102 or the one or more deployed services 104. The validation can be performed by the

At operation 214, the CA (Vault) 110 and particularly the plugin for SC CSR validation 112 performs validation that requestor runtime platform 102 is authorized to receive a new or reissued certificate. The plugin for SC CSR validation 112 is used to identify that the SC CSR 106 is self-contained and includes proof of identity of the requestor (e.g., runtime platform 102). The plugin for SC CSR validation 112 validates the integrity of the SC CSR 106, and uses the PC_1 to verify the signature of PuK_2 signed by Prk_1 which proves that PrK_2 is owned by the identity in PC_1. The identity should be runtime platform 102.

At operation 216, if the SC CSR 106 is verified and validated the CA (Vault) 110 sends the new or reissued certificate to the runtime platform 102. In certain implementations, IAM service 116 is provided with a identifiers as to public certificates or PCs. At operation 218, the process 200 ends.
